Title: Implement for cutting and bundling brushwood - has concavely shaped cutting and clamping jaws mounted for defined opening angle
Inventor: HABBIG HANS
IPC: A01G23/081
Filed: 1990-02-01
Abstract: The implement for cutting and bundling brushwood has cutting and clamping sections formed as shears (2) with blades (3) concave to the cutting centre (M), which overlap in the zone of the tilt-axis (4) of the two blades (3'). The free ends (9) of these have an opening angle of at least 80 degrees. The cheeks (8) of the clamping shears (2') have the same configuration as the cutting blades, and consist of at least two spaced cheeks on one side of the shears and at least one cheek on the other side.

Title: Heated solid state gas flow sensor combining compsn. measurement - by integration of reacting layer and heating track on the same substrate using thick-thin film techniques
Inventor: NOLTING PETER DIPL ING
IPC: G01F1/692
Filed: 1990-02-27
Abstract: The sensor (10) consists of a substrate (11) on which a heating element (12) has been formed as well as at least one gas-composition sensing layer (19) with electrodes (18) and a reactive layer (20). Also claimed is the devices in which at least one temp.  sensing layer (14) is present between heater (12) and chemical sensor (19). The construction consists of a heating element, pref. of a meandering shape, formed on the substrate, pref. ceramic, e.g. alumina, followed by an insulating layer (13), a temp. sensor (14), another insulating layer (17), electrodes for the compsn. sensor (18) and a chemically reactive layer (20). The reactive layer is pref. Sn-oxide or Ti-oxide, the gas passed over the sensor is pref. air. The device is mfd. using thin and/or thick film techniques. USE/ADVANTAGE - The sensor combines the function of compsn. sensor and mass-transport sensor, reducing the cost of the measurement functions. The device is easy to mfr. A simplification is to remove the temp. sensor electrode and use the heating element resistance as a temp. control. The device is used in the sensing of CO- or O2 content in air, e.g. in exhaust gases or in driving cabin air of lorries.

Title: Adsorbent and binder comprising comminuted rubber, esp. scrap tyres - for removing oil from water, sludge or soil
Inventor: JAEGER EUGEN
IPC: C09K3/32
Filed: 1990-03-10
Abstract: An adsorbent and binder, esp. for oil in and/or on water, comprises rubber chips, crumb, flour and/or flakes processed into the form of a mulch. The adsorbent is made from waste rubber, e.g. vehicle tyres, by comminution, e.g. by chipping, rasping or grinding.  The material contains at least 50 vol.% of air and the size of the rubber particles is below 1 mm (below 0.2 mm). USE/ADVANTAGE - The material is cheap and environment-friendly, floats and forms an adsorbent which floats and is easily disposed of, e.g. by burning, completely removes oil contamination, can be made from scrap tyres, and gives an adsorbate which is easily removed from a liq. surface. Oil is not washed out of the adsorbent by rain or ground water, but is gradually broken down bacterially; the adsorbent can therefore be left in an oil-contaminated sludge or soil.  The material can be used where oil contamination is to be expected, e.g. by leakage from tanks, or in pumping stations.

Title: Efficient sterilising of packaged foods in autoclave - where sterilising water is circulated between working vessel and storage vessel under control of water temp. and level in working vessel
Inventor: REUTER WALTER DIPL ING
IPC: A23L3/10
Filed: 1990-05-30
Abstract: Food items are sterilised in an autoclave system having a working vessel (1) and a water storage vessel (6) whose volume is several times the circulating water volume (3). Water is circulated between the two vessels and is heated or cooled by the addn. of steam (Dampf) or cold water (Kuhlwasser) as required. During the addition of cold water, a water level control (5) in the working vessel returns the water from this vessel to the storage vessel until a set min. temp. in the storage vessel is reached, after which time the excess water is run to drain (Abfluss). During the following sterilising cycle, water is returned from the storage vessel to the working vessel, and excess water is drained from the working vessel, until the storage vessel is empty or a pre-set min. temp. difference between the storage vessel and the working vessel is reached. Heating of the working vessel by steam then follows. USE/ADVANTAGE - Used for sterilising and cooling packaged foods. The quantity of heat recovered during the process is increased in relation to existing similar procedures, and the recovered heat is immediately available for use in the next sterilising cycle.

Title: Water cleaning basin - has oxygen@ delivery system at basin base to support plants which clean the water
IPC: C02F3/20
Filed: 1991-06-12
Abstract: For a biological cleaning action on soiled waste water, where the water flows through basins with plant roots to give a physical/chemical/biological cleaning, oxygen is introduced in partial zones of the base of the basin by mechanical or chemical delivery. Pref. mechanically delivered O2 is pure over pressure or compressed air passed to the base of the basin through porous tubes within the base from a closed tube feed. The porous tubes are laid across the water flow direction in a number of parallel or ring-shaped rows, according to the basin dimensions and shape. The porous tubes are covered by a coarse pore and/or loosely spread material such as ground plastics waste. The compressed air can be heated above its' compression heat, for winter use, using heated exhaust air from livestock buildings. The compressed air can be provided by a fan, or a blower powered by a wind wheel. In operation, the amt. of compressed air produced is altered by a control circuit according to the redox potential measurements at the base of the basin. O2 can be produced in an electro-chemical process, with a wind wheel to generate the electrical energy required. ADVANTAGE - The technique gives the correct conditions for the plant life and, in turn, their action on the water passing through for cleaning.
